创建更冷和更小的电源

1023 电源

在过去20年的电子产品分销工作中，我看到产品变得越来越小，而他们的能力却越来越大。
与此同时，我看到电子产品越来越依赖电池供电。
需要电池电源不仅支持处理器，还支持LCD屏幕，外围设备和传感器。
一个例子是将我的第一台计算机Tandy 3000与我目前的手机三星S8进行比较。
当Tandy 3000推出时它是高科技，它包含一个最先进的16位处理器，但小到可以坐在桌面上。
有一个独立的监视器和巨大的风扇来取代它产生的热量。
计算机和显示器都需要自己的电源，每个都比砖块大。
按照今天的标准，这台计算机是一个遗物。
我的S8有一个64位CPU，适合我的手掌，并且不需要大风扇试图让它保持凉爽。
这款手机具有集成屏幕，摄像头，GPS，无线功能，并且可以比Tandy更快地运行文字处理器，同时仅使用名片大小的电池作为其电源。
这让我提出三个问题：
产品如何变小？
球迷怎么了？
电池如何转换运行集成在产品中的每个组件所需的所有电量？
我在Maxim Integrated中发现了一个名为“满足小型设备功耗的大需求”的博客，该博客回答了我的一些问题，并提供了更酷，更小功率设计的解决方案。

Over the last 20 years of working in electronics distribution, I have seen product become smaller and smaller while their abilities have grown larger and larger. At the same time, I have seen electronics become more reliant on battery power. Battery power is needed to support not only the processor but also the LCD screen, peripherals, and sensors.

An example is to compare my very first computer, a Tandy 3000, to my current cellphone, a Samsung S8. When the Tandy 3000 came out it was high tech, it contained a state-of-the-art 16-bit processor but was small enough to sit on a desktop. There was a standalone monitor and huge fans to displace the heat that it produced. Both the computer and monitor needed their own power supply and each was larger than a brick. By today’s standards this computer is a relic. My S8 has a 64-bit CPU, fits in the palm of my hand, and doesn’t require large fans trying to keep it cool. The phone has an integrated screen, camera, GPS, wireless capabilities, and can run a word processor faster than the Tandy, while only using a battery the size of a business card as its power source.
This makes me ask three questions:

How does product keep getting smaller?
What happened to the fans?
How does a battery convert all the power needed to run each of the components that is integrated in product?

I came across this blog, entitled Meeting Big Demands for Power in Small Devices, from Maxim Integrated that answers some of my questions and offers a solution for cooler and smaller power designs.
